Specification of Letters Patent.

Patented Apr. 18, 1916.

App1ioation filed April 26, 1915. Serial No. 23,847.

To all whom itmag concern .Be it known that we, CHARLES A. PRICE andONLY. BENJAMIN SEFFENS, citizens of the United States, residing atMemphis, Tennessee, have invented a certain new and useful Improvementsin Side Bearings, of which the following is a full, clear, and exactdescription, such as will enablelothers skilled in the art to which itappertains to make and use the same, reference being had to, theaccompanying drawings, forming part of this specification, in which-Figure 1 is a side elevation of one form of our invention. Fig. 2 is alongitudinal sectional elevation. Fig.3 is a transverse sectionalelevation taken on the line 3-3 of Fig. 2. Fig. 4: is a longitudinalsectional elevation of a modified form. Fig. 5 is a transverse sectionalelevation showing another form. Fig. 6 is a fragmentary vertical sectionon line 66 of Fig. 5 showing substantially one half of the side bearing.Figs. 7, 8 and 9 are respectively a top view, side view, and transversesection of a third modified form.

The object of our invention is to provide an improved compensating sidebearing L springs 5.

having self contained means for centering the movable table of thebearing relative to the supporting portion.

As shown in Figs. 1, 2 and 3,.the preferred form of our inventioncomprises a base plate 1, which is provided with a supporting member 2.Upon the base plate 1 are formed lugs 4. On either side of member 2 andsecured to the lugs are centering A vertical flange 6 surrounds thesprings 5 and the supporting member 2. At its top, member 2 is providedwith a bearing member 7 of suitable hardened material presenting at itsupper side a bearing surface. The upper or table member 8 is providedwith a depending flange 9 which projects down below the upper edge ofthe flange 6 on the supporting member and is spaced apart therefrom atthe ends of the bearings to allow movement of the table member relativeto the base member. The table member is also provided with lugs 1Q towhich the springs 5 are attached at their upper ends. Secured in thetable member is an upper bearing member 11 which is adapted to rest uponthe bearing member 7 of the supporting member. Apertures 12 are formedin the depending flange of the table member and through them base pins14: are set in the lower member. The apertures 12 are of such size aspermits the longitudinal movement of the table member relative to thepins 1 1. The bearing is adapted to be secured to the truck bolster by asuitable attaching means which engages the flange of the lower memher 1and the bearing member of the body bolster is adapted to rest upon thetable member 8.v

In operationwhen the body of the car is alined with reference to thetruck bolster, the'car being supported by the center bearing normally noweight will be placed upon the side bearings andthe table member 8 willbe centered with respect to the lower member by. the springs 5 whichtend to maintain the upper bearing 11 upon the lower bearing 7. When,however, due to the relative shifting of the car body and trucks theweight is thrown on one of the side bearings and the car body movesrelative to the truck. the table member 8 will be shifted longitudinallyand the upper bearing member 11 displaced from the lower bearing member7, the springs compensating for the elevation of the truck, butyieldably supporting the car body to prevent oscillation thereof. Whenthe car body and trucks again come into alinement, the table member 8will be returned by the springs 5 and positioned with its bearing member11 on the bearing member 7 of the lower member. When the bearing member11 is displaced from the lower bearing member,' the table 8 will bedepressed against the tension of the springs 5 and thus affordcompensation for any addedelevation of the side of the truck affected.

The modification shown in Fig. 4 has substantially the same arrangementof table member 8 and lower member 1 with their corresponding verticalflanges. In this form, however, the. supporting members 2 ment withthelowerbearing members 2 yet are'in the form of transversely extendingwedges having convex bases which are seated inconcave seats 3 in thelower member 1. In this form, the bearing members 2 haveoonvex uppersurfaces and the upper bearing members 11 have concave lower faces whichtend to keep them in engageallow rocking movement between the two. Whena plurality of lower bearing members 2is employed as illustrated in Fig..4:, they are pivotally' connected by proper means such as the link13 which allows themto: rock together in their seats. Horizontal springs23 are secured atone end to the flange6 of the lower member and at theirother ends tosuitable lugs 15 on the supporting members 2. The tensionof the: springs. 23' tend to maintain'thesupporting members .2 inverticalposition and permits their rocking. movement longitudinally ofthe bearing. In this form, the upper bearing members 11- and thelowermembers 2 areinot' disengaged by the movement of the table member 8relative to the lower. mem-. ber 1 andfthe vertical compensationof the Itable member 8' is secured by'virtue'of the table'member'8 is provided''with a depend-' ing: wedge. member 19 which restsin the;

groove formed by beveled" portions 20v of:

' a the? friction members. Above the; bolt. 17,

the Wedge member is cut awayias sh'own-at.

22 in Fig. 6, toiaccommodate'; the" bolts when the wedge member.is-depressed. In; this form, when the weight isithrown upon thetableimember 8, it will be-rdepressed so" asito'. force the wedge member'19 between the frie tion member 16 which will yield laterally; against:the tension. of springs 18. In: this. action, the friction between thefriction member 16 and the baseplate 1 will tend to prevent the suddendepression of the table member 8. .When the pressure upon the tablemember 8is relieved, the friction meme bers' willbe forced inwardlybythe springs 18 and thus causeagradual return of thetablemember 8 to 1normal elevation. The tension of springs 18 may be controlled by v theadjustment of nuts 24 upon the bolts 17.

In the modified? form illustrated. inFigs. 7,8;..and:9iitbwillibezseensthatz bearing. meme bers 7 a and 11 arelocated on the table member and base member respectively at both sidesof the springs 5 In the form illustrated in Figs. 1,2, and 3, thesprings operate: to normally center the table member so that the thrustsof side movements of the car body will normally be carried by thesebearing members.
